EG4 12K Hybrid Solar Mini-Split

Neither, and that's the whole trick. The condenser has MC4 connectors that accept 90-380VDC directly from three or four panels (up to about 1,100W), so you wire panels straight to the unit and it air-conditions on pure sun. There's no inverter, no charge controller, and no battery bank in the loop — a dramatically simpler and cheaper setup than a conventional off-grid AC system.

If you have the 230V AC connection wired, the unit switches to grid power automatically and seamlessly — you don't touch anything, and the Solar Aircon app shows you the real-time solar-versus-grid mix. On a purely off-grid site with no AC backup, it only runs when the panels produce, which is fine for daytime cooling but means no overnight operation.

Yes — it ships with a pre-vacuumed quick-connect lineset, so there's no vacuum pump or gauges involved. The limitation is length: the lineset is a fixed 16.4 ft and can't be swapped for a longer run, so the condenser has to sit close to the indoor head. Verify your layout works within that constraint before ordering.

Not as a primary source in cold climates — heating is rated only down to 5°F. The 10.5 HSPF2 makes it an efficient heater in the shoulder seasons and mild winters, but if you need dependable heat below single digits, look at cold-climate units instead. Its natural habitat is sunny-climate cooling with heating as a bonus.

Not cleanly. The unit wants its own dedicated panels wired to its MC4 inputs — integrating with an existing whole-home array that's already tied to an inverter is clumsy and generally not worth the trouble. Most owners dedicate three or four panels to the unit and let the rest of the array do its normal job.
